Rolling
mill is a machine used for pressure shaping of metal and a range of
varied materials between rotating rolls (rolling). Broadly speaking, a
rolling mill plant is an automated system or line of machines that
perform both rolling and supplemental functions: transfer of the
original billet from the stock to the heating furnaces and the mill
rolls, shifting of the rolled material from one groove then onto the
next, turning, transport of the metal subsequent to rolling, cutting
into sections, stamping, trimming, packing, and shifting to the stock of
finished product.
History of Rolling Mill
The original continuous wide-band sheet mill was built in 1923 in the USA. Cold rolling of sheets was started in the 1880's, and the cold rolling of pipes was launched in 1930 in the USA. In the 1960's, the USSR, the USA, the Federal Republic of Germany, and Italy started work on foundry and rolling units that merge the procedures of continuous casting and rolling in one unbroken line. These units called continuous rolling mill, are now widely used in the fabrication of aluminum-alloy sheets, steel billets, and wire rod produced using aluminum and copper alloys.

Design and Classing
The key feature determining the design of a rolling mill is the plant’s function in respect to the range of production or the technological process. Depending on the range of production rolling mills are partitioned into billet mills (including plants that roll slabs and blooms), sheet and band mills, section mills (including beam and wire mills), as well as the mills that roll tubes and different parts (tires, wheels, axles).
Rolling mills are additionally classed based on their technological processes as casting and rolling units, mills for the reduction of ingots (including slab and blooming mills), reversing single-stand mills, tandem mills, multistand mills, continuous rolling mills, and cold-rolling mills. The size grading of a rolling mill designed for rolling sheets or bands is established by the roll body. The size grading of a rolling mill designed for billets and section metal is established by the diameter of the rolls, and that of a tube mill is established by the external diameter of the rolled tubes.

Conclusion
To conclude, the automation of the rolling mill processes ensures economy, efficiency, and quality of the finished products.
